[0030] For the data acquisition module 20 , when collecting and testing telecontrol information data and telecontrol configuration files, and performing communication link matching, it can be implemented specifically through the configuration file acquisition unit 21 , the telecontrol information data acquisition unit 22 and the communication link matching unit 23 .

[0031] The configuration file collection unit 21 is used to collect the telecontrol configuration file sent by the dispatching master station and import the telecontrol configuration file into the telecontrol information data collection unit 22; The telecontrol information data acquisition unit 22 is used to collect the test telecontrol information data sent by the dispatching master station according to the telecontrol configuration file and the preset acquisition cycle; The communication link matching unit 23 is used to match the communication links of the dispatching master station, the simulation master station and the simulation substation according to the telecontrol configuration file, and obtain the communication link verification code; wherein the communication link includes: from the dispatching master station to the simulation master station, from the simulation master station to the simulation substation, and from the simulation substation to the dispatching master station.

[0032] Furthermore, when the communication link matching unit 23 performs communication link matching and obtains the communication link verification code, it can be implemented specifically through the information identification code generation subunit 231, the separator generation subunit 232 and the link verification code generation subunit 233.

[0033] The information identification code generating subunit 231 is used to generate a first-level information identification code according to the communication link from the dispatching master station to the simulation master station; generate a second-level information identification code according to the communication link from the simulation master station to the simulation substation; generate a third-level information identification code according to the communication link from the simulation substation to the dispatching master station; It should be pointed out that the first-level information identification code, the second-level information identification code and the third-level information identification code are all binary codes.

[0034] The separator generating subunit 232 is used to generate a primary separator according to the primary information identification code and the secondary information identification code, and to generate a secondary separator according to the secondary information identification code and the tertiary information identification code; The link verification code generation subunit 233 is used to separate the primary information identification code and the secondary information identification code using a primary separator, separate the secondary information identification code and the tertiary information identification code using a secondary separator, and form a corresponding communication link verification code.

[0035] In this embodiment, the communication link verification code is a verification code for checking whether the communication links between the sender and the receiver are consistent. The data acquisition module 20 is also used to upload the test telecontrol information data and the communication link verification code to the data preprocessing module 30 for processing.

[0036] For the data preprocessing module 30, when performing preprocessing operations to obtain test telecontrol information preprocessing data, it can be specifically implemented by a binary transcoding unit 31, a delimiter generation unit 32, a to-be-processed data generation unit 33, a data block segmentation unit 34, a hash processing unit 35, a first initialization unit 36, a first offset inversion unit 37 and a data assembly unit 38.

[0037] The binary transcoding unit 31 is used to perform binary transcoding on the test telecontrol information data to obtain the test telecontrol information binary data; A separator generating unit 32, used to generate a primary separator according to the communication link check code; The to-be-processed data generating unit 33 is used to combine the communication link check code and the test telecontrol information binary data through the primary separator to form the test telecontrol information to-be-processed data; In this embodiment, the communication link check code is a set of codes used to check the accuracy of data transmission in the communication link, which can help detect whether errors occur in the data transmission process and improve the reliability of the data. The first-level separator can be a specific symbol or character, which is used to distinguish the communication link check code from the test telecontrol information binary data, and combine them together to form new test telecontrol information to be processed data. For example, first, the communication link check code can be generated according to specific rules. This process may include operations such as calculation, analysis and encoding of communication data. Then, a first-level separator is determined. This separator can be any pre-set character, such as a comma, a semicolon, a specific symbol, etc. Finally, the communication link check code and the test telecontrol information binary data are combined through a first-level separator. The combination method can be to put the check code in front of or behind the data, and use a separator to separate them to form a new whole, that is, the test telecontrol information to be processed data.

[0038] The data block segmentation unit 34 is used to segment the test telecontrol information to-be-processed data into test telecontrol information pre-processed data blocks according to a preset data segmentation rule; for example, the test telecontrol information to-be-processed data can be segmented in a front-to-back order of equal size to obtain a plurality of test telecontrol information pre-processed data blocks.

[0039] A hash processing unit 35, used to perform hash processing on each test telecontrol information preprocessing data block to generate a message authentication code; In this embodiment, the test telecontrol information preprocessing data block can be processed based on the hash algorithm, so that whether the information is tampered with during the information transmission process can be detected, thereby achieving the purpose of improving the accuracy and authenticity of the information data.

[0040] The first initialization unit 36 ​​is used to perform initialization operation on each test telecontrol information preprocessing data block and generate a unique corresponding initialization vector, thereby ensuring that each test telecontrol information preprocessing data block is unique, thereby improving the uniqueness of the information.

[0041] The first offset reversal unit 37 is used to generate a unique corresponding conversion offset k for each test telecontrol information preprocessing data block, and shift the characters in each data block backward by k positions, and return the characters beyond the database boundary to the beginning, thereby improving the security of the information.

[0042] The first offset reversing unit 37 is further used to reverse each character of the offset test telecontrol information preprocessing data block according to a preset data reversal rule. For example, the data block is reversed once according to the length of every three characters. When the characters in the data block are an integer multiple of three characters, normal reversal is performed; when the characters in the data block are not an integer multiple of three characters, the remaining characters are not reversed.

[0043] The data assembling unit 38 is used to assemble the obtained groups of initialization vectors, the obtained groups of message authentication codes and the obtained groups of inverted test telecontrol information preprocessing data blocks into data packets to obtain test telecontrol information preprocessing data.

[0044] The data preprocessing module 30 is also used to upload the obtained test telecontrol information preprocessing data to the data verification and analysis module 40 and record the uploading time.

[0045] For the data verification analysis module 40, when performing verification analysis to obtain the integrity index, it can be specifically implemented through a time recording unit 41, a moment verification unit 42, a data splitting unit 43, a second initialization unit 44, a second offset reversal unit 45, a data recovery unit 46, a hash verification unit 47 and an integrity index generation unit 48.

[0046] A time recording unit 41, used to record the reception time of the test telecontrol information preprocessing data; The time verification unit 42 is used to verify whether the receiving time is consistent with the preset time interval; if it is not consistent, it means that the current test telecontrol information preprocessing data is abnormal; if it is consistent, further verification and analysis are performed on the test telecontrol information preprocessing data; The data splitting unit 43 is used to split the test telecontrol information preprocessing data to obtain the corresponding initialization vector, message authentication code and test telecontrol information preprocessing data block; A second initialization unit 44, used for re-initializing each split test telecontrol information pre-processing data block to ensure that each data block is unique; A second offset inversion unit 45 is used to perform offset inversion again on the initialized test telecontrol information preprocessing data block to obtain a test telecontrol information preprocessing data block after offset inversion; The data recovery unit 46 is used to recover the test telecontrol information preprocessing data block after the offset inversion to obtain the original test telecontrol information preprocessing data block; for example, the test telecontrol information preprocessing data block after the offset is moved forward by k positions according to the conversion offset k.

[0047] The hash check unit 47 is used to perform hash processing on the test telecontrol information preprocessing data block after the recovery offset inversion, generate a new message authentication code, and compare and check the new message authentication code with the split message authentication code; if the message authentication codes are consistent, it means that there is no difference between the new test telecontrol information preprocessing data and the original test telecontrol information preprocessing data; if they are inconsistent, it means that there is a difference between the new test telecontrol information preprocessing data and the original test telecontrol information preprocessing data; The integrity index generating unit 48 is used to compare and analyze the original test telecontrol information preprocessing data and the new test telecontrol information preprocessing data to obtain an integrity index representing the degree of data consistency.

[0048] The data verification and analysis module 40 is also used to upload the integrity index to the abnormal data prediction module 50 for training and updating the telecontrol information data abnormality prediction model.

[0049] For the abnormal data prediction model, when constructing the abnormal prediction model and performing abnormal prediction, it can be implemented specifically through the prediction model construction unit 51 and the abnormal prediction unit 52.

[0050] The prediction model building unit 51 is used to build a telecontrol information data anomaly prediction model based on the integrity index of the historically collected telecontrol information preprocessing data; When constructing the telecontrol information data anomaly prediction model, the prediction model construction unit 51 can mark several groups of historical integrity indexes through the sample set generation subunit 511, and generate a training sample set using the historical integrity index; wherein the training sample set includes a sample set and a test set; and then the model training subunit 512 uses the training sample set to train the standard anomaly prediction model constructed based on the convolutional neural network to obtain the telecontrol information data anomaly prediction model.

[0051] In this embodiment, several groups of historical integrity indexes can be labeled, for example, p = 0, 1, 2, 3, ..., o, where o is a natural number. Then, the feature set of h groups of historical integrity indexes in p is extracted as a sample data set, and the sample data set is used to obtain the sample data mean, which is recorded as a sample set. Further, the remaining groups of historical integrity indexes are used as a test set, and the sample set and the test set are used to form a training sample set. Then, a standard anomaly prediction model is constructed based on a convolutional neural network, and the obtained training sample set is imported into the standard anomaly prediction model for training. After training, a telecontrol information data anomaly prediction model is obtained.

[0052] The abnormality prediction unit 52 is used to input the real-time collected test telecontrol information data into the telecontrol information data abnormality prediction model and output the abnormality prediction result.

[0053] In this embodiment, the output of the telecontrol information data anomaly prediction model is the data range deviation. For example, if the data range is 3-6, and the data range in the database is 5-8, the difference range output by the model after difference comparison is 3-5 and 6-8.

[0054] The abnormal data prediction module 50 is also used to upload the abnormal prediction result to the real-time management module 60 .

[0055] For the real-time management module 60, when it performs data management according to the abnormal data results, it first determines whether the data range deviation of the test telecontrol information data output by the telecontrol information data abnormal prediction model is within the preset abnormal interval threshold range, such as determining whether the above-mentioned difference range is within the preset abnormal interval threshold range; if so, it means that the test telecontrol information data is normal, that is, the communication link between the dispatching master station, the simulation master station and the simulation substation is normal and can be used normally; if not, it means that there is an abnormality in the test telecontrol information data, that is, the communication link between the dispatching master station, the simulation master station and the simulation substation is abnormal, and a corresponding early warning prompt message can be generated at this time to remind the staff to check.

[0056] Of course, it should be pointed out that the system provided by this solution should be connected to the monitoring and coordination platform of the substation, or configured in the monitoring and coordination platform of the substation.
